Sign-in required, tools not seen, not counted. The MCP endpoint listed for Sentry at mcp.sentry.dev answered 401 with OAuth metadata on 4 November 2026. Its tools can be listed only after a person authorizes a client, and this directory never signs in.

The endpoint answered the handshake with a sign-in challenge, so the tool list is not visible to this directory. It is not counted as an MCP server: a sign-in challenge is its own state, and the connector listed no tools.
Connector log
2 connections on 4 November 2026, read-only methods only
19:55:51Z https://mcp.sentry.dev/mcp sent initialize result auth-required (HTTP 401) 117 ms

Request https://mcp.sentry.dev/mcp without a token. It answers 401 and a WWW-Authenticate header.
Read the protected resource metadata at https://mcp.sentry.dev/.well-known/oauth-protected-resource/mcp to find the authorization server.
Register a client at the registration endpoint https://mcp.sentry.dev/oauth/register (dynamic client registration), so no human has to create an app first.
Send a person through the authorization page, then retry the endpoint with the bearer token. The connector stops after step 2 and never authorizes.
